To all whom it may concern .1.

Be it known that I, DdNALD Emma, a

citizen of the Dominion of New Zealand,

A chainber connected to a supply of Wa- 1 ter under pressure has an outlet communicating with a spraying nozzle and a cylinder in which is a piston connected by a flexible medium with a weighted lever carrying a clapper valve adapted to close the said outlet. 7

The movement of the pistonunder pressure of water in the chamber causes the lever to be raised and the supply ofwater to the spraying nozzle to be out ofi.

A single apparatus may be employed or the lever may be fixed to the plug of the stop cock which is opened to admit water to a second apparatus. Any desired number of apparatus may be thus connected. together.

The invention will now be more particularly described by reference to the accompanying drawing.

Figure 1, is a longitudinal sectional elevation showing the positions of the parts before admission of water to the apparatus. Fig. 2, is a longitudinal sectional elevation showing the positions of the. parts, after a predetermined quantity of water has passed passed through the apparatus. Fig. 3, 1 a plan of the lower part of the apparat s, Fig. 4:, an elevation, and Fig. 5, a sectional elevation of a regulating plug. Fig. 6, an enlarged sectional plan on line fir-A, Fig. 1, and Fig. 7, a sectional elevation of a sprayer.

The chamber 1 is connected by a pipe 2 to a high pressure water supply and has ordinary stop cock (not shown on the drawing). The pipe communicates with the chamber 1 by the port 8. A pipe 7 connects MPMA'Z'US FOR $PRAYIIhl'Gfli-ABDENS, ROADS, AND LIKE.

the chamber to a pipe 8, to which is attached Any suitable sprayer maybe employed and Ihave shown in Figs. 1, 2 and 6, a constructionof sprayer which is not of my in vention, wherein a pipe 9 has a fixed cap 10 the top of which is open. has a lixed guide block ll. I

A p1pe'12 having fixed upon its lower end a tubular guide 13 is slidable through the block 11 and has a bell mouthed end l4. A

from a block 16 which is fixed within the for the pi ssage of water.

A dis l8 integral with thespray producer" closes down upon the top of the cap when the sprayer is not in operation The pipealso conical spray producer 15 projects upwardly pipe 12 and has channels 17 in its periphery In bringing the sprayer into operation the pressure of thewater projects the pipe 12- telescopically beyond the pipe 9 until" its movements are limited by contact "of -.the guide 13 with the block 11. i

A. cylinder 20 connected to the chamber 1 is fitted with a piston21 which hasre:

versed bucket washers 22 and 23. A chain 24 attached at one end to the lower end of the piston 21, "is attached at its other end to a weighted lever 25.

A rod 26 connects th per valve 27, the stem 28 of whiohenters a cup 29 formed upon the top of the rod.

A pin [30 passes through a slot 31in the lever 25 to a claps stem 28 to enable-the clapper valve to move p freely in a "-iateral direction within a recess formed by making a shoulder 32 at thebase of the pipe A. reservdir 35 connected to the cylinder 20 by a screwed union 36 is provided with,

a screwed cap 87., through which a stem 38' projects and is fitted with wings 39. A plug 40 screws into the union 36 and is fixed to the stem 38. The plug has a cavity tzand at its base has a valve seating 43. A 'valve' 44 adapted to close upon the seating 4371s guided by its stem 45, which passes freely into a hole 46 formed in the top of the plug. The valve is prevented from falling out of the plug by a pin 47 passing through the plug and through a slot in the stem 4C5;

A groove 49 tapering in width and depth from its larger and lower end is cut vertically across the screw threads of the plug.

In operation the cylinder 20 is first filled the valvedi upon its seating.

The pres'sure of wa ter forces the piston 21 into its cylinder'QO, and the Watercontained in the cylinder is forced through the groove 49 into the reservoir 35, the pressure of the water closing The time which the piston takes to rise in its cylinder is regulated by adjusting the plug. -10 in the-union- 36 so that thetapered groove 49 is opened to a greater cr'less degree for the @asSage-of the water. The period of travel for the" piston can also be determinedby the length of the cylinder 20. The supply oflwater rin 'eylinder 20 is maintained by the slightesca e past the bucket washers 22 .a ndz'23. -The-piston 21 while rising draws uf-itlwschain 24 and raises the lever 25,-

A pipe fififleading from th'fe'oock 58 to the chamber manner other'apparatus may-be connected I to work in series. The water passes from the pi e 2, through the chamber 1 and throng the pipe 59 to a second apparatus constructed similarly to the apparatus herein described, the clapper valve and the piston meanwhile remammg in their raised positions.

When the cock'in the pipe2 is closed, the reduction of the pressure allows the piston 21 and the clapper valve 27 to falhand by the fall voi the piston'the Water contained in the reservoir 35 escapesthrough a port 'lntothe cavity 42 and past the valve 44 back into the cylinder 20 thereby leaving the apgaratns ready for further use. The water isplaced by the fall ofthe piston escapes through the sprayer, the clapper valve fal1- in from its seat beforethe piston descends.

, he sprayer shown'in Figs. 1, 2 and 6,

operates by the water pressure forcing' the P1136112 telescopically through the pipe 9 until its movement "is arrested by contact of the guide '13 with the block 11." The cap 10 is. then raised a considerable height from the ground. y

Fig. 7 shows a sprayer which is used when my invention is employed for spraying roads and comprises a box 50 having a cover 51,

upon the cover 51.

nozzle'rises-only' a short distance above the constantly under the in said chamber, an outlet pipe leading from The presvalve, said connection through a tapering hole/in which slides a cylindrical nozzle 52 having sprayin holes 53. The nozzle has a beveled valve iace 54 adapted to close upon a seating 55 formed Normally the nozzle 52 is in such a position that the spraying holes 53 are lower than the cover 51 of the box. The Water pressure raises the nozzle 52 so that Water passes through the holes 53. The

ground and if struck by the wheel of a vehicle the 'nogzle is temporarily pressed into. the cover, the tapering hole therein facilitating the movement of the nozzle.
